We don't drain the pipes when we are there. The design allows us to turn the heat down (to 55) when gone and put a hair dryer right on any issues we have. Plus draining the system takes about 3 mins. Still I believe that with the heat turned up it helps when temps hit 20 below.
For me when Iook at the pipes I see beauty and functionality, I don't mind looking at them at all.
